THOMAS C. FINOH, OF MADISONVILLE, OHIO, ASSIGNOR TO THE AUTO- MATICPRINTING PORATION.

MACHINE COMPANY, OF CINCINNATI, OHIO, A OOR- HAND PRINTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 771,900, dated ob r 11,1904. Application filed March 21, 1904:. Serial No. 199,214. (No model.)

T at whom, it may concern.-

Be it known that I, THoMAs O. FINoH, a citizen of the United States,residing at Madisonville, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in HandPrinting-Machines, of which the following is a specification.

My invention relates to a hand printingpress.

The features of my invention are more fully set forth in the descriptionof the accompanying drawings, forming a part of this speci fication, inwhich Figure 1 is a side elevation of my hand printing-press. Fig. 2 isa central vertical section of the same. Fig. 3 is a top plan view of thesame, illustrating one side of the frame.

A represents the skeleton frame. B represents the inking-rollerjournaled therein. O represents the type-roller journaled in the framecontacting the inking-roller. D rep-. resents the platen -roller. Erepresents a belt-roller. F represents an endless carrier passing overrollers D E. G represents a roll of paper in the rear of roller E, thepaper being adapted to be fed upon a belt F and so carried under thetype-wheel. H represents a crank-handle fixed to the axis of the rollerD. In order to conveniently support these rollers in a frame so thatthey are readily removable and insertible, I provide the followingdevices: 1, 2, and 3 represent journal-boxes for the axes of the rollersE, O, and B, respectively. These boxes have the adjustment-screws 4:, 5,and 6 and the tensionsprings 7 and 8. For each end of each roller theskeleton frame is provided with the internal guideways a, fitted toreceive the adjustable journal-boxes 1, 2, and 3. In order to slide thejournal-boxes into these guideways a, each guideway is provided with asecond guideway (Z, wider than the journal-box and adapted to admit ofthe ready insertion or removal of the journal-boxes. It will be observedthat the ribbed portions 6 c it, which form the guideways d, are widenedor flared, which facilitates the ready separation or insertion of therollers, with their journal-boxes, relative to the skeleton frame.

It will be seen that the roll of paper G is wound on an axis that issupported in inclined guideways, so that the weight of the roll keeps itin contact with the concave shelf under the roll, and henceautomatically furnishing a frictional contact to prevent the paper fromrunning off of the roll too freely when the unwinding strain is placedupon it.

As the driving or pulling element of paper is the crank H of roll D andas the printing is done upon the endless belt, it is necessary that thebelt-carrier E be adjustable to and from the driving-roller D, so as tokeep the endless belt taut and to preserve a smooth surface on which toprint. Hence the slidable journal-boxes are an essential feature, andthese boxes must work in guides and the frame portion cut away, so as toallow the ready removability of the roll. The cut-away portion (Z beingat the inner end of the guide- Way toward roller D allows thejournal-boxes to be moved inward far enough to slack the endless belt,but not to remove the roller.

The type roller has to be frequently changed or taken out for theinsertion of a new roller or a new type. Hence the cutaway portion is inthe front of the frame and away from the inking-roller, allowingsufficient space for the journal-boxes to be moved into the forwardcut-away portion. By this means the inking-roller can be readily renewedand adjusted to the exact position, the carrier-belt can be readilyrenewed, and the perfect cooperative adjustment of all of the parts canreadily be obtained.

The paper is drawn off by hand from the roller G, carried over theendless belt F, and held against the same while the operator turns thehandle H and drawsthe paper on the belt between the platen andinking-roller. The slidable boxes of the printing-roll of thecarrier-roll are then adjusted so as to obtain the requisite tautnessand friction. By this means uniform printing is readily obtained and themachine quickly adjusted to the thickness and texture of the paper to beprinted.

Having described my invention, I claim 1. In a hand printing-machine, aninkingroller, a contacting type-roller and a carrierroller respectivelymounted on sliding journals, a platen-roller, an endless carrier-beltconnecting the last two named rollers, the belt on the platen-rollerfrictionally engaging the type-roller, a paper-roll mounted in inclinedguides in front of the carrier-roll, and a crank-handle on theplaten-roller, substantially as described.

2. In a hand printing-machine, a skeleton frame, guideways for slidablejournal-boxes adjustably mounted therein, an inking-roller, atype-roller and a carrier-roller respectively journaled in the slidableboxes, a platenroller supported in fixed journals, an endless beltconnecting the said platen and carrier roller, and a paper roll mountedupon an axis in front of said carrier-roll, substantially as described.

3. In a hand printing-machine, a skeleton frame having Ways formedtherein and a cutaway portion at the end of each of said Ways,adjustable and slidable journal-boxes mounted in said Ways, a carrierroller, a printingroller and an inking roller respectively mounted insaid slidable journal boxes, a platen-roller and an endless beltsupported on said carrier and platen roller, a handle on theplaten-roller, substantially as described.

4. In a hand printing-machine, a skeleton frame, the ribs thereof havingformed on the inside guideways for the reception of the inking, platenand carrier rollers, respectively, each guideWay beingformed integral inthe frame with an enlarged opening at one end thereof and flaredlaterally, substantially as described.

In testimony whereof I have hereunto set my hand.
